' Myirivention relates to vending machinesior roll material; the machine being; designed ini'- tially andprimarilyfor'vending screen wire". One of the objects of the invention is -the pro- 5 vls'ionofa support for any number of rollsor wire and' ofany desired lengths. Another object of the invention is the provision of a support'which will protect/the "rolls of wire from being bent or jammed or from being injured in any other way. I 1

Another of the objects is the provision 'of a support which will maintain a plurality of rolls of wire in almost instant readiness tobe -meas ured'and cut.

5, It isalso my object to so design thesupp'ort that no handling of the wire roll isnecessary after the roll has been onceinstallediso that there will be no necessity of removing the roll from the support until the entire roll is consumed. g

It is my object also to not only make the support serve as a perfect protector of the wire cloth but to also greatly reduce the time and labor necessary for vending the material. 7

Another object of the invention is the provision of a support which maintains the wire roll at its normal diameter so that it cannot expand while on the support. 7

Having in view these objects and others which will be pointed out in the following description, I

' reel and showing also the rounded top edge of the frame over which the wire is drawn;

The reel includes two discs 10 which are united in spaced apart and parallel relation by means of the outwardly concave troughs 11. While these may be made of any desired material, my preference is for steel discs and for sheet metal troughs of the kind used on the edges of roofs. The troughs 11 may be in any desired number from three up, the number depending on the maximum number of rolls of screen wire to be carried by the support.

The rolls of screen wire are indicated by the numeral 12. These rolls are seated in the troughs 11 as shown in Figure 2. In order to prevent the displacement of the rolls 12 from the troughs 11,

I provide rods 13 in the form of bolts passing '55 the reel. The reel is also provided with a central shaftl4 which passes through-both 'discs-lll and which issecurely connected"with the disos 10jso that the discsand the shaft rotate-'as 'a unit One end-of the'shaftis' provided-witha cranli handle 15as shown in Figure l. i

The support-for the re'elis in the form 015a simple open frame having 'front -cornen-posts' 18 and rear corner posts 17; These corner-posts are connected by means of transverse braces-as shown in Figure 1 althoughthe arrangementbi the braces maybe altered at will. In-my preferred' construction I arrange the transverse braces in the form of open shelves! for sup'port ing' the rolls of screen wire which areikpt in stock and which are thus readily available for insertion inthe reel. Theirame is provided with a pair" of bearingiblocks 1arorfcne shaft 14. "A pin 19 is slidable through one of the'bearing blocks 18 to "cooperatewith one of aplurality of concentric apertures 20 in one of the discs 10 for locking the reel against rotation in any desired operativeposition.

The upper ends of the posts 16 are connected, by means of a half round 21, this being parallel j to the axis of rotation of the reel. The scale 22, I

also connects the front corner posts 16 andit is calibrated to indicate the width of the wire in the roll, thus furnishing a convenient device for indicating the desired roll when the reel is turned. A vertical scale23 is secured to one of the two corner posts 16, preferably the one at the right, and this enables the operator to.

measure ofi the desired length of screen wire.

In use the rolls of screen wire are secured to the reel by passing the rods 13' through-their middle portions and then fastening the rods to the discs 10 by means of nuts. When the customer desires screen wire. of a specific length and width, the crank handle 15 is turned until the scale 22 indicates that the roll of the desired width is in position.v The pin 19 is then pressed in to latch the reel against further rotation. The free end of the wire on the roll is then grasped in the hands and is withdrawnfover the top rounded edge of the half round 21 and the strip is measured against the scale 23. The measured length of wire may then be cut off by means of tin snips or other suitable cutting apparatus, the framebeing provided with an elongated transverse opening at 24 for the easy manipulation of the-shears. This opening 24 also cooperates with the scale 23 in insuring that the desired length of roll material be measuredand cut ofl with reasonable accuracy. Another im-' portant function of the opening 24 is that the rot roll material may be cut at a right angle to the edges of the material. The scale 23 is horizontal while the corner post 16 is vertical, the two being thus perpendicular to each other. The importance of this function resides in the fact that the corner post 16 with his left hand while he severs transthematerial with a pair of shears with the verse opening 24 as a guide. 7

The rolls are held in place in the troughs 11 by means of the rods 13 which serve as axes for the rolls, The troughs 11 ordinarily, hold the material against unwinding. When the roll becomes small indiameter, however, it is very apt toiunwind'suddenly and to fall out. To prevent such unwinding and to keep the roll in more compact condition, I secure resilient presser members 26 torthe troughs l1; in'a manner suchthat they will bear against the material in the roll. These presser members 26Umay be in any of several different forms but those which I have illustrated consist of spring steel rigidly, secured ,to the troughs and having rounded free ends which readilypermit the turning of the roll in either direction but which prevent any unwinding oftheroll j ,p v WhileI have described my, invention as particularly applicable to the dispensing of screen wire or; wire cloth of all kinds, it is obvious that withwpossibly slight changes in dimensions the support may be used for vending wire fencing, poultry netting, oilcloth, building material, linoleum, dry goods and other material which is available in roll form. It may also be used in shipping departments and similar places as a support for wrapping paper. Although I have confined myself in the description to the one specific use with screen wire, I wish it to be understood that I reserve to myself the right to employ the support to any and all uses for which the support is adapted.

Having thus described my invention in such full, clear, andexact terms that its construction and, operation will be readily understood by others skilled'in'the art' to which it pertains, What I claim as new and desire to secure by Letters Patent of the United States is:

In a vending machine for roll material, a support having front, rear and side members in rectangular relation and having supporting legs at the corners thereof, a shaft journaled in said side members,a reel secured to said shaft be-,

tween said side members, said reelincluding a pair of discs'with a plurality of channel members connecting said discs, rods releasably secured between said discs and positioned in the arcuate centers of said, channelmembers, said rods being adapted to support rolls of roll material, said front member of said support having a rounded upper edge and a transverse slot therebeneath, means for latching said reel against rotation with the supporting rod of any desired roll positionedbelow the level of said front member of said support, and fixed'transverse and, vertical scales at the front of said support for indicating the width and the length of the piece of roll material to be cut off.
